makes a new net-cscf module. ini
inj : expected max size of input for preallocation of
internal states ki0
kj0 : kernel size for first convolutional layer
tbl0 : table of connections between input anf feature maps
for first layer si0
sj0 : subsampling for first layer ki2
kj2 tbl2 : same for last
convolution layer outthick : number of
outputs. prm an idx1-ddparam in which
the parameters will be allocated.
